I use lxd to host containers for running CI jobs, which take ~10 hours to complete sometimes. A frequent failure mode is something along these lines causing ‘lxc exec’ to drop out:
Error: read tcp 10.50.72.13:51440->10.246.64.5:8080: read: connection timed out
I’m not sure if this is due to underlying network issues or something else; perhaps the lxd snap being restarted?
Should this be reliable? Is this a reasonable use case for lxd exec? Any ideas what might be happening?
